DJI Completes TB55 Battery Investigation
Enhanced Firmware Ensures Optimal Performance
January 16, 2019 — In a significant development for drone enthusiasts and professionals alike, DJI has successfully finalized its investigation regarding the reports of certain TB50 and TB55 batteries indicating incorrect power levels late last year. The investigation followed concerns raised about potential risks associated with these batteries, prompting the company to take proactive measures. Now equipped with updated firmware (v01.02.0301), DJI assures customers that the firmware effectively resolves the issues that previously led to early Return-To-Home (RTH) and Automatic Landing (AL) scenarios.
The innovative firmware update introduced a redundancy algorithm to the battery management system, which has proven successful in mitigating earlier problems linked to conservative safety measures employed by DJI during its investigation. This upgrade not only restores confidence in battery reliability but also enhances the overall user experience.
Testing Results Reinforce Battery Efficacy
After extensive testing and diligent performance monitoring, DJI confirmed that the current firmware, released in December, sufficiently addresses the concerns raised. As a result, there will be no need for additional updates this month. Users who have previously updated their TB55 battery firmware can operate with peace of mind, knowing they are using a reliable product. Further testing indicated that these improvements also provide enhanced protection for drones operating with older battery models and in low-temperature conditions.
Commitment to Performance and Reliability
DJI remains steadfast in its commitment to delivering powerful and dependable drone solutions across the globe. The company continues to explore and implement new strategies aimed at improving product performance through upcoming firmware updates, reinforcing its reputation as a leader in the drone industry.
Compatibility Reminders for Drone Pilots
Important Notice: Pilots utilizing drones from the DJI M200 series and the DJI Inspire 2 equipped with TB50 batteries may still encounter an “inconsistent firmware” notification if their batteries are updated with various firmware versions. This discrepancy can lead to drone lockouts. DJI recommends pilots ensure that all batteries in use are updated with the same firmware version to avoid compatibility issues and to enhance the user experience.
Best Practices for Battery Maintenance
As with any lithium battery, a variety of factors can influence usability, including age, total power cycles, external conditions like weather, and optimal storage and handling practices. DJI encourages pilots to consult the Intelligent Flight Battery Safety Guidelines and adhere to the updated user guidelines to minimize any potential disruptions, particularly when flying drones equipped with older battery models or when operating in frigid temperatures.
